' DOOR CHECK OR STOP Fnd Aug. 6, 1929 14 of the car' bod Patented May 6, 1930 eA-rsT orrlcs ALBEBT C. EABHAB'I', HEIGHTS, OHIO DOOR CHEGZK 03 STOP Application filed August 6, 1989. Serial H0. 383,805.

' 10 or wood construction.

A further object is to provide a door check which is neat in appearance, easy to install, and in which the cushionin member may be readily replaced when it comes worn or 15 dead and which is constructed so that-there will be no rattling of the parts under the vibrations of the automobile onwhich they may be used.

In the drawings I have illustrated one form of my invention wherein Fig. 1 is a horizon tal sectional view throu h the door check mounted in the door and ody of an automobile; ,Fig. 2 is a horizontal sectional view showing the relative position of the arts 25 when the door is open; Fig. 3 is a vertica sectionalview through the check taken on the line 3-3 of Fi 2; Fi s. 4 and 5 are sectional detail views ta en on ines 4-4 and 5--5 respectively of Fig. 3. I

The door stop of my invention comprises a pair of brackets or anchor members in the form of narrow receptacles rovided with outwardly extendin flanges 12 y which they are attached to the oor stile and post 13 and with screws 15or bolts when desired or w on the automobile body is of all metal construction. In the latter case, the opposing edges of the door and door frame are provided with openings of a 'size 49 to receive the receptacle portions 10 so that the flanges 12 may be secured to the outer or inner faces of the door. The door is hinged in its frame by the usual type of car hinge illustrated at 16.

Pivoted in one end of one anchor member 10 isa U-shaped link made from sheet metal, the free ends of which are provided with aligned apertures for the rece tion of the pivot pin 21 which ]passes throng and is secured in the side wal of the receptacle or anchor member. At its op osite end the U- shaped link is provided wit aligned slots 22 in which a pivot pin 24 is slidably received, and to the outer ends of which are secured fiat metallic links 25, the opposite ends of which have aligned a rtures for the reception of a pin 26 by which they are pivoted 1n the end of the other receptacle or anchor member 10.

Interposedbetween the closed end 27 of the U-shaped link 20 andthe center pivot pin 24 is a rubber cushioning block 28 against which the pin 24 strikes when the links 20'and 25 are extended suddenly so that the sudden stop of a rapidly o ened door is cushioned. as The block 28, it will be noted, is provided at its opposite edges with lips or flanges 29 which engage over the edges of the U-shaped bracket so that it will be held securely in place, as illustrated in Figs. 4 and 5.

The 0 eration of the device is clear. The receptac es or anchor members 10 are secure- 1y fastened in the edges of the door and stile so that when the door is closed they are in opposed relation forming a housing for the-7i links 20 and 25. When the dooris opened the links straighten out, and as they are moved to their limit, the pin24 moves against the rubber block 28 cushioning the jolt which would otherwise result with a rigid pivot con" nection. I L

In the form illustrated, the links 20 and 24 have their outer ends disposed at an angle I to the body of links so that when the links are extended, the 'pivot 24 is not in alignment with the pivot pins 21 and 26. By this arrangement the links will never come to a dead center so that the door will not close, and they will always fold together in the right direction as the door is closed.

While I have described In invention as being particularly applicable or doors of the present day motor vehicles, it is obvious that they may be used on any typewf door, the size of course being varied to suit the condi tions.

The door-stop described is neat in a pearance and is readily installed. Since t e anchor members 10 and links 20 and 25 are made from sheet metal, they are readily 1'00 stamped or drawn so that the cost of manufacturing is kept at a minimum.

\Vhile I have illustrated'onlyone form of device it will be obvious that various changes 5 may be'made in its construction without dc parting from the spirit. of the invention or the scope of the appended claims.

Having thus described my invention, what I claim is m 1. A door check comprising a pair of attaching members, a pair of links, one pivoted to each member, a pivot pin secured in one of said links, the other link having a slot through which said pivotpin passes, and a resilient member held in said slotted. link aga nst which the pin strikes as it moves in its slot when the links are extended to their limit.

2. A door check comprising a pair of brackets, a U-shaped sheet metal link pivoted at he open end to one of said brackets. there being aligned slots in said link near its closed end, a second link pivoted to the other of said brackets, a pin passing through said slots and secured in said second link connecting the links together for limited longitudinal movement relative each other when in extended position, and a resilient member interposed between the closed end of the U-shaped link so and the said pin against which the pin strikes.

in testimony whereof, I hereunto ailix my signature.
